Understanding the 500 Internal Server Error on a Linode-Hosted Website

A Linode-hosted website that displays the generic HTTP status code 500 Internal Server Error means that it has encountered an unforeseen circumstance that has stopped it from completing a request. Because it doesn’t identify the specific issue, this error serves as a catch-all for server-related problems. The error appears as follows:

What are the Error Impacts?

A 500 Internal Server Error may have the following effects:

• Website downtime: When users are unable to access the website, traffic and income may be lost.

• User Frustration: The user experience and reputation of the brand may suffer if visitors grow irritated and depart the website.

• SEO Impacts: If search engines consistently find faults when crawling a website, they may devalue it.

• Business Operations: Since customers are unable to finish transactions, this issue may result in lost sales and revenue for e-commerce websites.

Error Common Causes & Fixes

1. Incorrect File Permissions

Files or directories may not have the right permissions, preventing access.

Fix:

i. Set directory permissions to 755 and file permissions to 644. We can do this using an FTP client or via SSH with the following commands:

For directories:

chmod -R 755 /path/to/directory

For files:

chmod -R 644 /path/to/file

ii. Then, we use the command below to verify:

ls -l

2. Corrupted .htaccess File

The .htaccess file may have invalid settings or errors.

Fix:

i. We need to rename the file to see if that resolves the issue:

mv .htaccess .htaccess_old

ii. Then, visit the website to check for improvements.

iii. If we use WordPress, regenerate the .htaccess file by going to Settings > Permalinks and clicking Save Changes.

3. PHP Memory Limit Exceeded

The website may be using more PHP memory than allowed, often due to heavy plugins or scripts.

Fix:

i. Locate the php.ini file with:

php -i | grep php.ini

ii. Then, open it:

nano /path/to/php.ini

iii. Increase the memory limit by adding or modifying this line:

memory_limit = 256M

For WordPress: Edit wp-config.php:

nano /path/to/your/wordpress/wp-config.php

Add this line before /* That’s all, stop editing! Happy blogging. */:

define(‘WP_MEMORY_LIMIT’, ‘256M’);

iv. Restart Web Server:

For Apache:service apache2 restart

For Nginx:service nginx restart

4. Faulty Plugins or Themes

A malfunctioning plugin or theme can cause errors.

Fix:

i. Disable All Plugins:

cd /path/to/your/wordpress/wp-content/plugins/
mv plugin-name plugin-name_old # Rename each plugin folder to disable it.

ii. Then, check the site to see if the error is fixed.

iii. Revert to Default Theme:

cd /path/to/your/wordpress/wp-content/themes/
mv your-active-theme your-active-theme_old # Rename the active theme.

iv. Reactivate Plugins One by One. We must turn plugins back on individually to find the culprit.

5. Server Configuration Errors

Incorrect server settings can lead to errors.

Fix:

i. Check for Syntax Errors:

For Apache:

apachectl configtest

For Nginx:

nginx -t

ii. Review Server Logs: Check logs for detailed errors.

For Apache:

tail -f /var/log/apache2/error.log

For Nginx:

tail -f /var/log/nginx/error.log

iii. Correct Any Errors in configuration files (like httpd.conf for Apache) and restart the server:

For Apache:

service apache2 restart

For Nginx:

service nginx restart

6. PHP Timeouts

Scripts may exceed the maximum execution time allowed.

Fix:

i. Find the php.ini file:

php -i | grep php.ini

ii. Open the file:

sudo nano /path/to/php.ini

iii. Change the max_execution_time to a higher value:

max_execution_time = 300

iv. Restart the Web Server:

For Apache:

sudo systemctl restart apache2

For Nginx:

sudo systemctl restart nginx

By following these steps, we can identify and resolve the causes of a 500 Internal Server Error, ensuring the website runs smoothly.

Prevention Steps

To stop a 500 Internal Server Error from happening again on a website hosted by Linode, we must;

• Keep regular backups of the databases and website files so we may restore earlier iterations in the event of an error.

• Use monitoring tools to maintain tabs on server resource utilization and adjust scripts and plugins appropriately.

• Keep the server software, plugins, themes, and CMS up to date to prevent incompatibilities that can result in errors.

• Include thorough error logging in the server settings to facilitate speedier diagnosis and resolution.

• Test changes in a staging environment before implementing them on the live site.
